# Pulse Energy ↔ Avg Power calculator

Convert between pulse energy, average power and repetition rate.

Category: [Unit Converters](https://aperioptic.com/calculators)

Formula: `Pavg = Epulse · frep`

## Inputs

| Input | Parameter | Unit | Default |
| --- | --- | --- | --- |
| Pulse energy | `E` | µJ | 10 |
| Rep rate | `frep` | kHz | 1000 |

## Result with the default inputs

- Avg power: 10 W
- Avg power: 10000 mW
- Period: 1000 ns

Open it with your own values: put each input in the address as a parameter, for example [`/calculators/pulse-energy-avg-power?E=10`](https://aperioptic.com/calculators/pulse-energy-avg-power?E=10). A unit other than the listed one goes in `<parameter>_unit`.
